Is the square root numbers rational or irrational?
It depends. If a number is a perfect square or a ratio of perfect squares then its square root is rational. If not, the square root is irrational.For example,Consider 9/4. Since 9 and 4 are both perfect squares, the square root of their ratio is rational. sqrt(9/4) = 3/2 or 1.5. But this is less obvious if the number is presented to you as sqrt(2.25)
